Remote Monitoring and Control

Modified on: Tue, 5 Apr, 2016 at 11:28 PM

Every AIRSYS controller (ASLLC) deployed in the US is set up for remote monitoring and control as a standard
feature. This basic access to the HVAC system is available via a serial port utilizing a Modbus communication
protocol. For Verizon Wireless sites, this means that any 3rd
party gateway system (eg. Site Boss 500 or 3200RMX) can
collect this information and report in a variety of formats.
Typically this reporting is done via a dashboard GUI (Graphical
User Interface) that provides a convenient, intuitive method for
looking at real time environmental parameters such as temperature
and humidity or exercising control over the system (eg.
switching the Lead/Lag roles by command).

The AIRSYS controller allows remote viewing of a great deal of system information such as:

Run time of all major functions (Free Cooling, Mechanical Cooling, Supply fan, etc.)

Remote monitoring and control is a very important step toward understanding these systems better and
finding ways to reduce their cost of operation. Please contact the HVAC support team if you have any questions
on the remote monitoring and control capabilities of the ASLLC.2 Lead/Lag controller
